20230099735 · 2023-03-30 ·

A system and method for managing and controlling power of base station when a connectable terminal device is moving at speed through the coverage area of the base station, the method obtains a transmission power from a terminal through the base station; obtains location of the terminal, and generates a transmission power conversion table according to the terminal transmission power and the terminal location. The transmission power conversion table is transmitted to the terminal by the base station, the transmission power being used by the terminal according to the transmission power conversion table, avoiding repeated communications and electrical energy cost between base station and terminal in respect of the changing location of the terminal.

UPPER LAYER DESIGN FOR RELEASE 16 MIMO ENHANCEMENT

Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.
